- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
Explanation:
The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:
- Net rate = rate of filling - rate of leaking
- Net rate = 5 liters/minute - 1 liter/minute
- Net rate = 4 liters/minute
Thus, consiedering the tank is empty at the beginning, the time is:
- Time = Volume of the tank / net rate of filling
- Time = 10 liters / (4liters/minute)
- Time = 2.5 minutes ← answer
I don't know about the circle, but from the way it looks, you can use pythagorean theorem (A^2+B^2=C^2). angle E would be the Right Angle making 65=C or in other words, the hypotenuse, with 60 and Line ED being the legs (it doesn't matter which is A and which is B) leaving the equation
60^2+B^2=65^2 and solve from there. (if you need help solving, leave a comment and i will walk you through it in the comments)
To find the decimal form, you have to manually divide 1 by 8. Since 8 is greater than 1, the quotient would then start with 0., then you add a 0 next to 1, to make it 10. This time, divide 10 by 8. The nearest answer would be 1, because 1 *8 = 8. Subtracting this from 10, you get 2. Add another 0 to 2, to make it 20. Do the cycle all over again. The complete solution is as follows:
0.125
---------------------------
8 | 10
- 8
------------------------
20
-16

40
- 40

0
<em>Hence, the decimal form of 1/8 is 0.125.</em>
Answer:
Step-by-step explanation:
8×3cuartos:648
2nd angle measures 50
90 is the total so all that was needed is to subtract 40 from 90
